Immediately after purchasing an 05 LGT with 84K on the clock it turns out that the #2 Exhaust valves were pulverized and no longer making a decent seal against the seats. Once the tech tore the heads off he found that #4 wasn't much better and the #1 and #3 cylinders were starting to show the same signs of deformation.
I have been told by the dealership that this issue is rare on these cars but just this last week another LGT was brought in with that same issue to that dealership. And I was told by the tech that my new valves will more than likely suffer the same fate as the originals due to the hardness of the valvesprings on those motors.
So this is making me wonder if this is an issue that anyone else has been running into yet?
I'm wondering if this issue is only rare because it's more rare to have an 05+ LGT with that many miles
